Porn star and director Michael Lucas has been slapped with a federal lawsuit after making waves with an XXX remake of the classic movie “La Dolce Vita” that features a steamy public frolic in a New York fountain.

The company that owns the rights to Federico Fellini’s 1961 award-winning film “La Dolce Vita” has accused Lucas of dirty dealing by making a gay-porn version of the classic movie that violates trademark laws and tarnishes the original’s reputation.

Lucas drew media attention in September when he briefly took over City Hall Park to allegedly recreate a famous fountain scene from “La Dolce Vita,” jumping into the water for a make-out session with his co-star, Savanna Samson.

Lucas denied ripping off Fellini’s flick.

“The similarities are so little, I would say it was maybe inspired,” Lucas said.
